Your OpenAPI spec is already a test plan — here's how to turn it into Playwright tests automatically
Short summary
A developer built a free tool that converts OpenAPI 3.x specs into ready-to-run Playwright test files, generating happy path, auth, validation, and contract tests per endpoint. The tool reads required fields and security schemes directly from the spec to produce meaningful assertions. It targets teams already using TypeScript and Playwright who want fast API test bootstrapping.
- •Tool generates Playwright API tests from OpenAPI specs automatically
- •Produces four test types per endpoint: happy path, auth, validation, contract
- •Free, no login required; built with Vite + TypeScript on Vercel
Generated with AI, which can make mistakes.
